### Summary In the macOS companion app (**currently beta**), a parsing mismatch in exec approvals could let shell-chain payloads pass allowlist checks in `system.run` under specific settings.

### Impact This path requires all of the following: - authenticated caller with `operator.write` - paired macOS beta node host - exec approvals set to `security=allowlist` and `ask=on-miss`

Under those conditions, a shell-chain command could be approved from an incomplete command view and then executed on the paired macOS host.

### Default Install Status Default installs are not affected.

### Affected Packages / Versions - Package: `openclaw` (npm) - Affected: `<= 2026.2.21-2` - Patched (planned next release): `>= 2026.2.22`

### Technical Details The fix hardens macOS allowlist resolution by evaluating shell chains per segment and failing closed on unsafe shell-substitution parsing in allowlist mode.

### Product Status Note The affected macOS companion app path is currently in beta.

### Fix Commit(s) - `5da03e622119fa012285cdb590fcf4264c965cb5` - `e371da38aab99521c4e076cd3d95fd775e00b784`

### Release Process Note `patched_versions` is pre-set to the planned next npm release (`2026.2.22`) so once that version is published, this advisory can be published without additional metadata edits.
